metals

A

group 1 and 2
usually bond
are givers

19
Q

non metals

A

share electrons

20
Q

double bond

A

when elements share more then one electrons

21
Q

covelant bond

A

sharing a pair of valence electrons by 2 atoms

can form between atoms of same and diff element

22
Q

2 types of valence electrons

A

polar and non polar

23
Q

polar covalent bond

A

non equal

one atom will be pulling more and one will be pulling less

24
Q

ex of a polar covalent bond

A

water

25
Q

non polar covalent bond

A

equally electronegative

sharing electrons equally

26
Q

componds

A

combination of 2 or more elements

27

Q

hydrogen bonds

A

hydrogen atoms is covalently bonding to one electronagative atom

29
Q

are hydrogen bonds strong or weak

A

weak

30
Q

electronegativity

A

an atoms attraction for the electrons in a covalent bond

31
Q

why in a molecule will functions be based on shape

A

bc it has a shape

32
Q

chemical reactions

A

the making and breaking of chemical bonds

33
Q

reactants

A

what you put in a chemical reaction

34
Q

products

A

what comes out

35
Q

halogen

A

salt

36
Q

mettaloids

A

have multiple charges

have properties of both metals and non metals

37
Q

isotopes

A

same elements but diff mass

38
Q

noble gases

A

have similar properties

39
Q

van der wall atractions

A

when 2 molecules that both have unstable elements get together and are attracted to each other
